The search for the neutrino, the Universe’s most elusive ingredient

Forty years ago Ray Davis and John Bahcall tunnelled deep into the Earth to build a trap for the most elusive particle in Nature – the neutrino. It was an experiment which few thought could ever succeed, and it produced a result which no one believed. But for decades Davis and Bahcall refused to give up – convinced that they were on to something important. This is the story of how their experiment led to an astonishing discovery which is making scientists re-think their most fundamental theories of what the Universe is made of, and where it all came from.
